FENCE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,892, dated November16; 1886.

2 Application filed Septemherj, 1886. Serial No. 212,967. (No model.)-

To all whom it may concern.-

' United States, and residents of Richmond, in

the county of Wayne and State of Indiana, have invented certain new anduseful Improvementsin Fence-Machines, of which the following is aspecification.

' Our invention relates to fencemachines which are employed to twistwires around slats, building the fence in position for use, the variousobjects of which will be more fully set forth in the description of theaccompanying drawings, making a part of this specification, in which-Figure 1 is a perspective view of our improvement in position for use.Fig. 2 is aside elevation of the supporting-frame. section of thetwisting device on line a," .r, Fig. 1. Fig. 4 is a perspective view ofthe framebracket; Fig. 5, a sectional elevation of the adj usting-clamp.Fig. 6 is a top plan view of the top gage and suspending-clamp. Fig. 7is a bottom perspective View of the same. Fig. 8 is an end view of theupright frame and adjustable gearing. Fig. 9 is a perspective view ofthe top gage. Fig. 10 is a perspective view of the adjustable tubularwire eye. Fig. 11 is a similar view of a bracket to which saideye isattached. Fig. 12 is aplan view of the framebracket for connecting thesupporting-frame sill, ground-wheels and uprightframe brace.

1 represents posts or uprights forming an open frame upon which theintermediate and connected together, there being a bracket, 6,

at each end of the sill or frame, one being the counterpart of theother.

7 represents a recess formed by ribs 8, into which one end of sill 2fits.

9 represents a hole through which the cen- Fig. 3isa.

.turns.

tering stud-bolt 10 passes. This bolt secures the sill 2 to bracket6,and extends sufficiently through said sill and bracket to form a stud onwhich ground wheel 3 journals. 11 represents a recess for securing oneend of segment at to said bracket.

12 represents flanges or ribs against which the edges of the segmentabut to hold it firmly in position. 13 represents a bolt-hole throughwhich a bolt passes, rigidly connecting said segments to said'brackets.

The supporting frame is composed 'of sill 2,

segment 4, and the two brackets 6, and the four bolts uniting the partstogether.

In order that the loom or upright frame may be adjusted at differentangles from the vertical, we provide the following adjusting de vices:Upright frame 1 is hinged by pivot 5 to the supporting-frame on which itnormally 11, Fig. 5, represents a through-bolt passing throughframepiece 1. 15 represents a clamp pivoted to said framel. .16represents a set-nut engaging the threads on bolt 14. Segment 4. playsbetween post 1 and clamp 15, and is secured thereto by means of nut 16,which when turned draws clamp 15 against the segment 4 and post 1. It isdesirable to have the tops of the slats even. To obtain this result wehave employed an adjustable gage-plate, 17. which is adj ustably securedupon bracket 18 by means of a slot, 19, pierced in the shank of thegage-plate. a slot in said bracket 18, through which slot a bolt, 23,passes. The foot or L part of this gage-plate 17 serves as a stopagainst which the top of the slat rests. In order that the slat may bereadily inserted and held in this position, we provide .springclamp-arms 21, which are secured to' the loom-frame at one end-andextend outward in a curved form, so as to form a clasp at the throatformed by the reversed curved fingers 21, between which the slat isthrust and held by the retractile force of the spring. Thus the slatsare readily inserted and held at a uniform plane at the top until thewires are twisted to hold them 'permanently, and readily released as themachine is drawn backward. In order that the ends of the brackets 6 ofthe supporting-frame may not catch against 20 represents ICO whichjournals in bracket 26 on post 1. 41,,

be laterally adjustable therein. the disks 24 set farthest apart.

Fig. 3, represents a collar suitably connected to the hub of thetwisting-wheel and overlapping the bracket, and thus securing thetwisting-wheel against the face of the bracket and allowing it torevolve within the periphery of the rim therein. 27, Fig. 11, representsa slotted bracket rigidly SGClllGdiJO the face of I the twisting-gears.28 represents adjustable eyes, each having an elongated slotted shank,through which is passed a clamping-bolt, 29, which may likewise securebracket 27 to twisting-disk 24. 30 represents a semi-tubular extensionof the eyes passing through the slot in bracket 27, so as to form anelongated bearing to support the wires, which are twisted by therevolution of disk 24. 40 represents an enlarged portion of the slotnear the end where the wire presses in working, and through which knotsin the wire may be passed without cutting the wire, as is requiredinmost devices heretofore made. In order that these twisting-disks may beadjusted vertically, we provide a series of transmi tting-gears, 31,which are'journaled to slotted bracket 37, so as to Fig. 1 shows Fig- 8shows transmitters 31 set to the right to bring the twisting-disksnearer together, hence diminishing the distance between the wiressupporting the slats. The transmitters 31, having teeth 011 theirperipheries of the same pitch as disks 24, allow of this adjustment, andthe entire series are driven by a single crank, 34, which drives bevel35, journal'ed on one end of the crank-shaft and meshing with thebevelteeth 36, formed at the periphery of one of the transmitters. Theobject of these bevels is to allow crank 34 to revolve in a planeparallel with the vertical plane of the fence.

By using intermediate transmitters, 31, and the twisting-disks 24, weaccomplish two results-first, these wheels are lighter than when largetwisting-disks are employed with peripheral teeth transmitting motionfrom one to the other; second, it allows of their being verticallyadjusted to readily regulatethe distance between the wires.

The various devices herein shown are simple, cheap, and effective intheir operation. The slotted eye 28 allows a ready adjustment betweenthe wires to accommodate difierent thicknesses of slats. Thesemi-tubular extension 30 holds and delivers the wires in a bettermanner than other devices.

Our entire machine is light, strong, and durable.

We claim 1. The combination, with an upright frame carrying twistingdevices, of the sill 2, pivoted to the lower end of said frame, thesegmental brace 4, adjustable on said frame, the groundwheels 3, and thebrackets 6, connecting said wheels and brace to the sill, substantiallyas described.

2. The combination of the twisting-frame 1, the pivoted sill 2, havingwheels 3, the segmental brace 4, pivoted clamp 15,through-bolt 14, andset-nut 16, substantially as described.

3. The combination of the twisting-frame 1, pivoted sill 2, adjustablesegment brace4, and the brackets 6, having recesses 7 and 11, forconnecting the sill and brace, substantially as described.

4. The combination ofthe upright wire-twisting frame, the spring-clamp21, and gage 17, for suspending the slats at their top in a uniformplane, substantially as specified.

5. In combination with the top of the up right frame, thevertically-adjusting gage 17, and spring-clamps 21, located beneath saidgage, substantially as specified.

6. The twisting-eyes 28, provided with the semi -tubular extension 30,substantially as specified.

7. The twisting eye28, provided with the enlargement in its slot for thepassage of the knots in the wires, substantially as specified.

8. In combination with the twisting-disk 24, the slotted bracket 27, andthe twistingeyes 28, having an elongated slotted shank, and asemi-tubular extension, 30, substantially as described.

9. The combination of the upright frame 1, slotted brackets 26,twistingdisks 24, slotted brackets 27, eyes 28, having semi-tubularextensions 30, and the bolts 29, substantially as described.

10. A wire-twisting loom composed of the vertical frame 1, the alternateseries of twisting-disks 24,having vertically-adjustable beariings, andprovided with teeth on their peripheries,and the series of transmitters3l,arranged alternately between the twisters, provided withlaterally-adjustable bearings, and driven by a crank and bevel-pinions,substantially as specified.

In testimony whereof we have hereunto set our hands.
